Physical control of Weeds
Physical control is the removal of weeds by physical
or mechanical means, such as mowing, grazing, mulching,
tilling, burning or by hand. The method used often depends
on the area of weeds to be managed, what the land is
used for, physical characteristics and the value of
the land. It is important that, when using physical
control, any item that can move from a weed-infested
site to an un-infested site, such as machinery, vehicles,
tools and even footwear, is cleaned free of weed seed
before moving, to stop the spread of weeds to new areas.
As with most control methods long-term suppression of
weeds requires follow up weed prevention.
Hay making, mowing and grazing
Hay making, mowing and grazing before weeds produce
seeds restrict the amount of weed seed in an area and
reduce the spread of weeds.
Mulching, by covering the ground with a layer of organic
material, suppresses or kills weeds by providing a barrier
between the weeds and sunlight. Mulching has an added
advantage in that it improves the condition and moisture
level in the soil. Planting competitive and desirable
plants that provide a dense cover over the weeds suppresses
weed growth in a similar way to mulching.
Tilling, the ploughing or cultivation method that turns
over the soil, buries the weed beneath the soil. This
provides a barrier to the sun, therefore killing the
weeds. Tilling is a form of physical control that can
be easily undertaken over a wide area, using agricultural
machinery. This method is useful for making soil ready
for planting new crops, but it can lead to damage in
soil structure and exposes the soil to erosion and further
invasion by weeds.
Burning removes the above-soil body of the weeds killing
most of the plants. If carried out before seed is set
it can prevent the further spread of weeds. Burning
can be undertaken over a wide area with minimal human
input. As with tilling, burning exposes the soil surface
to erosion. If burning is used as a control method,
caution should be exercised to minimise the risk of
harm to the environment and to those undertaking the
Removal by hand, including hoeing, is a good method
for selective removal of weeds without disturbing the
surrounding desirable vegetation. It is very labour-intensive
and is often only used in small areas, such as gardens
or in larger areas during bush regeneration.
